basic-cli 0.28.1

app [main!] { pf: platform "https://github.com/roc-lang/basic-cli/releases/download/0.28.1/7brgwR8YUqfeGrkdfF1V4GPPN7DnP7ftqub9KcrTEZtr.tar.zst" }

Use Roc nightly-2026-11-13-03dce41 or later. CI, release builds, and the
Nix development shell now use this nightly.

Fixes

• Cmd and Path check without duplicate-definition warnings on the new
  nightly (#556).
  Cmd.Command remains opaque and keeps all its builder and execution methods;
  the Cmd.call!, capture!, run!, and spawn! convenience functions keep
  their existing signatures.
• The pinned compiler includes the Windows unwind-table fix in
  roc#12996. This resolves the
  compile-time failures of quoted Locale and Path values reported in
  #555. Applications using
  0.27.0 or 0.28.0 also benefit from upgrading the compiler; their literals do
  not need changing.
• The platform header now explicitly types main! arguments as List(OsStr),
  matching the native arguments supplied by the launcher
  (#554).

Source validation now checks the platform with --no-cache on Linux and
Windows, so dependency warnings and compile-time literal failures fail CI.
Linux runtime checks use the official nightly and verify static PIE loading
and development-backend callbacks.
